Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
Key

1. At least 12 years of age
2. Completion of the ACH471-201 clinical study OR diagnosed with biopsy-confirmed primary C3G or IC-MPGN
3. If a pre-treatment biopsy is obtained, or if a historical biopsy is available for review, it must have no more than 50% global fibrosis and no more than 50% of glomeruli with cellular crescents
4. Clinical evidence of ongoing disease based on significant proteinuria (defined as =500 mg/day of protein in a 24-hour urine) attributable to C3G disease or IC-MPGN in the opinion of the principal investigator (PI), and present prior to study entry and confirmed during Screening
5. If on corticosteroids, anti-hypertensive medications, anti-proteinuric medications (for example, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers), or mycophenolate mofetil, must be on a stable dose for at least 2 weeks prior to screening
6. Female participants must use an acceptable method birth control to prevent pregnancy during the clinical study and for 30 days after the last dose of study medication
7. Male participants must use highly effective birth control with a female partner to prevent pregnancy during the clinical study and for 90 days after the last dose of study medication

Key exclusion criteria
Exclusion Criteria

1. Have a history of a major organ transplant (for example, heart, lung, kidney, or liver) or hematopoietic stem cell/marrow transplant
2. Have a history or presence of any clinically relevant co-morbidities that would make the participant inappropriate for the study (for example, a comorbidity that is likely to result in deterioration of the participant's condition, affect the participant's safety during the study, or confound the results of the study), in the opinion of the PI
3. Have an eGFR <30 milliliter/minute/1.73 m^2 at the time of screening or at any time over the preceding 4 weeks
4. Is a renal transplant recipient or receiving renal replacement therapy
5. Have other renal diseases that would interfere with the interpretation of the study
6. Have evidence of monoclonal gammopathy of unclear significance, infections, malignancy, autoimmune diseases, or other conditions to which C3G or IC-MPGN is secondary
7. Have been diagnosed with or show evidence of hepatobiliary cholestasis
8. Females who are pregnant, nursing, or planning to become pregnant during the study or within 90 days of ACH-0144471 administration or participants with a female partner who is pregnant, nursing, or planning to become pregnant during the study or within 90 days of ACH-0144471 administration
9. Have a history of febrile illness, a body temperature >38°Celsius, or other evidence of a clinically significant active infection, within 14 days prior to danicopan administration
10. Have evidence of human immunodeficiency virus, hepatitis B infection, or active hepatitis C infection at Screening
11. Have a history of meningococcal infection within the prior year
12. Have a history of hypersensitivity reactions to commonly used antibacterial agents, including beta-lactams, penicillin, aminopenicillins, fluoroquinolones, cephalosporins, and carbapenems, which, in the opinion of the investigator and/or an appropriately qualified immunology or infectious disease expert, would make it difficult to properly provide either empiric antibiotic therapy or treat an active infection.
13. Have participated in a clinical study in which an investigational drug was given within 30 days, or within 5 half-lives of the investigational drug, whichever is longer, prior to the first dose of ACH-0144471
14. Have received eculizumab at any dose or interval within the past 50 days prior to the first dose of ACH-0144471
15. Have received tacrolimus or cyclosporine within 2 weeks of the first dose of ACH-0144471
16. Have a 12-lead electrocardiogram (ECG) with a QT interval Fridericia correction formula >450 millisecond (msec) for males or >470 msec for females, or have ECG findings which, in the opinion of the PI, could put the participant at undue risk
17. Have received any drug known to prolong the corrected QT interval within 2 weeks of the first dose of ACH-0144471 and which, in the opinion of the PI, could put the participant at undue risk
18. Have any of the following laboratory abnormalities at screening:

* Alanine transaminase > upper limit of normal (ULN)
* Aspartate aminotransferase > ULN
* Absolute neutrophil counts <1,000/microliter
* Total bilirubin >1.5* ULN
* Indirect bilirubin > ULN
* Any laboratory abnormality that, in the opinion of the PI, would make the participant inappropriate for the study
19. Unwilling or unable to comply with the study protocol for any reason
